To aZZ whom it may concern:

Be it known that we, GEORGE H. BUSHNELL and OSCAR P. BUSHNELL, both of Worcester, in the county of WVorceste'r and State of Massachusetts, have inventedjcertain new and useful'Improvements in Presses; and we declare the following to be a description of our said invention. sufficiently full, clear, and exact to enable others skilledin the art to which it appertainsto make andusethe same, referencebe ing had to the accompanying drawings, which form a part of this specification.

The objects of our present invention are to provide a press for making cider and wine, and for other purposes,which can be operated with facility and economy, and on which a large amount of material can be pressed in a given time; to provide a revolving or swing platform with two pressing-tables, either of which can be brought'into position beneath the press ing-follower at pleasure, and to afford facilities for conveniently shiftingthe platform as required 5 to provide a delivery for the liquid or juices from the pressing-tables at a position and in a manner that will not'interfere with the working of the revoluble platform, and which will give efficient discharge from each of the tables at any positionof adjustment; to provide means for raising the platform or tables from the bed of the press for allowing of its convenient movement when the pressing mechanism is relieved, as more fully hereinafter explained. These objects we attain by mechanism substantially such as shown in the accompanying drawings, and hereinafter described, the particular subj cot-matter claimed being hereinafter definitely specified.

In the drawings, Figure l is a plan view of the lower part of a press embracing our improvements. Fig. 2 is a front view of the same. Fig. 3 is a plan view of the bed-plate on which the platform revolves. Fig. 4. is a vertical sec tion through the discharge-passages and axial center. Figs. 5 and 6 are detail views on largerseale, showing the manner of supporting the revolving platform at the bed of the press. Fig. 7 is a bottom view of the revolving platform, showing the details of construction. Fig. 8 is a vertical section at line w 10, showing on a larger scale the manner in which pressing is going on on the first table.

theparts may be joined. Fig. 9 is a vertical section at line x x, and Fig. 10 is a perspective view of the press complete. p

In the references, A denotes the bed or lower head of the press, and B B the standards or rods that connect the upperand lower heads together and sustain the strain of the pressing apparatus, the mechanism for which may be of any suitable construction for imparting the necessary pressure in a convenient manner. We prefer for this purpose a knuckle-joint and screw pressing apparatus of the construction shown in 'Fig. 10,' or of the nature described in Letters Patent No. 266,967 but we do not wish to confine our present invention solely to presses of this kind, since it is equally applicable to some other classes of press.

. C denotes the revolving platform, circular at the central portion, and formed in the present instance of heavy wood planks'about four inches in thickness, with a central metallic ring or circle, D, which fits onto an annular bed-plate, pivot, or center piece, E, located and supported at one end of the bed A in such manner that the wings of the platform, which carry the pressing-tables G O",will swing over the bed A, between the standards 13 and B, for bringing either one of the pressing-tables to a position in the press where its contents can be acted upon by the'descending follower F,while the other one of said tables is ata position outside the press where it can be conveniently loaded and unloaded while the operation of The bed-plate E is made with an annular flange, 6, which fitsinto a recess, (1, in the lower edge of the ring D, and forms a seat on which the ring D revolves. Said bed-plate E is bolted firmly to the end of the bed-timberAor pressframe.

GEORGE H. BUSHNELL AND OSCAR P. BUSHNELL, or wononsrmt, ass."

The platform 0 may be made, as shown in top of the platform 0 the pressing-tablesO O occupy corresponding positions at opposite sides of the central ring D, the inner edges of said tables extending slightly over the side of said ring. The ring D embraces or surrounds.

the two press-standards B in such manner that the tables can more completely around" their circle of motion without interfering with; The tables C C are pro the said standards. vided with a rim or guard, g, of proper height to prevent the overflow of juice or liquid, except at the point of discharge, where a passage, f, is-formed just over the central ring, D, at

whiehplaee the guard g is omitted and the edge of. the-tableis hollowed out, and also fit ted with. a drip-lip, f, -to prevent the liquid; flowing back onthe under surface of the table. 5 A pan or receptacle, K, fills the space within the ring -D,'leaving only sufficient room for freedom of action.

tables 00 revolve about it. The edgcsof thetpanKextend up back of the drip-lips f, so thatthe pan receives all the liquid that' drains from both-the tables at whatever;posi- The standards B are'iitted tion they occupy. with proper guards, b, to direct the flow into thepan when the passage f swings past said standards. A disehargepipe, 'K", is connected with the receptacle K, which pipe may lead out at one side of the apparatus, or to such other convenient position as may be desired,

for the delivery of the liquid as it runs from thepress. By arranging the delivery-passage through the axial center of the platform, a single delivery serves for both tables, and the liquid can discharge as readily while the table is revolving as when at rest in pressing position.

exert a yielding force for lifting the platform 0 free from the surface of the press-bed A.

The roll-bearing-i is mounted on a spring,- m, having sufficient strength or tensionto lift about three tons, more or less, or somewhat more than the weight of the platform and table, together with the load of material to be pressed thereon, so that while the platformis being shifted it simply rests on the roll I ,but

when the follower F is forced down for pressing the material the spring m yields and allows the platform C to rest solidly upon the bed A..

Then when the press-follower is again-raised and the pressure relieved the expansion of the spring m again raises the roll I, so as to support the platform free of the bed A. In the present instance the spring on is set within a rectangular box, a, beneath the bearing 43, which latter is retained by pinsZ across its Said pan rests upon the bed-plate E stationary, while the ring D and be employed, if desired, and sueh'rolls may be located at other position in relation to the bed A than herein shown without departure from the nature of our invention, the essential feature of which is a yielding support for the platform for raising it free from the press bed, except when the press is operating.

In order that the platform 0 may be depressed to the bed A with facility, the track G is provided with recesses h h, (see Fig. 7,) corresponding in position with the positions of the supporting-rolls H that are nearest to the bed A when the pressing-tables are in working position, and so arranged that when the pressing-tables are brought into proper alignment beneath the follower the said supporting-rolls runinto the respeetiverecesses h h, releasing their support on the track G at that point, and permitting the depression of 0 other rolls H are set to run onthe center of the track, so that only the particular rollsintended can run into the recesses h h,.thus giving support for the platform at all positions, except at the one position where depressionis required. A shaft, M, having a pinion,.M, is arranged at a convenient position for revolving the platform. The pinion meshes with the annular gear G, and the shaft extends beyond the sweepof the platform 6. .Oirthe end of the shaft M is a large sprocket-wheel, N, connected by a drive-chain, .N, with a small sprocket-wheel, 0, supported atthetop of a suitable bearing-standard, P, and provided with a hand-crank, R, by means of which the platform 0 and tables CU can be conveniently revolved or shifted. On the bed Awe arrange a lifting-roll, 1, (one or more, as desired,) that is adaptedto' sire to secure by Letters Patent, is-

l. The combination, with the bed A,standards B, and pressing mechanism, substantially as shown, of the platform 0, carrying pressingtables 0 C", mounted for rotative actionona pivot or axial bearing-plate at or near one end of the press-bed, and a drainage-receptacle, K, and discharge-pipe K, located at the axial position for receiving the liquid from the: press, as hereinbefore set forth.

2. In a press for making cider, wine, oil, &c, the combination of two or morepressing tables swinging or rotating about the end standards of the press, and adapted for discharging toward their axis of rotation, and a stationary circular pan or receptacle embrac IIO ing the press-standards and extending beneath the edge of said table, for receiving the juice or liquid from each of said tables at any position of their movement or adjustment, sub stantially as set forth.

3. The combination, with the press-bed, the strain-rods, and the pressing mechanism in a press substantially such as described, of the platform 0, having pressing-tables 0 C the track and gear GG, the supportingrolls H, the pinion M, and means for operating the parts, substantially as set forth.

4. The combination, with the-press-bed A and revolving platform 0, of the bed-plate E, having the bearing-flange c, and the ring-bearing D, having the recess d, substantially as and for the purpose set forth.

5. The combination, with the ring-bearing D, bed-plate E, and tables 0 C of the discharge-pipe K, the receiving-pan K, with rim a, and the overhanging lip f, substantially as set forth.

6, In a press for extracting juice or liquids, a revolving platform carrying a series of pressing-tables having an axial bearing embracing both of the two standards B B at one end of the press-bed, and adapted for complete or continuous revolution in either direction, substantially as hereinbefore set forth.

7. The combination, with'the bed and shifting platform in a press, of a yielding bearer or roll adapted for raising the platform free from the surface of the bed when the force of the press is relieved, and for yielding and allowing the platform to rest solidly on said bed 3 5 when the pressing force is applied by the follower, as hereinbefore set forth.

8. The combination, with the bed A and platform 0, of the roll I, its bearing 1', the spring m, and box n, substantially as and for 0 the purpose set forth.
